Having the usual defrost issues with my RS21. I replaced the fridge sensor recently which helped, but after a few days a new error code appeared.
At first it was just the middle bar on the fridge side, I was told I needed a new defrost heater, which I stupidly paid the guy £58 pounds for (Tony Clifton @ Airkool), and he's never sent it and now stopped answering my text messages.
Anyway, got a little off topic there!
The error code is currently the middle and top bars on the fridge side. I've already replaced the fridge sensor and the evaporator cover. What do I need to do next? Do I need the defrost heater, and if so, is this the correct one: http://shop.ukwhitegoods.co.uk/product_ ... ts_id=1067
